CKMT1 Counteracts VDAC1 Oligomerization‐Induced Neuronal Pyroptosis Through Steric Hindrance in Ischemic Stroke

open access: yesAdvanced Science, EarlyView.
CKMT1 inhibits VDAC1 oligomerization via a dual‐region mechanism: its NTD interacts with the VDAC1 C‐terminal domain, while residues 1–39 sterically hinder dimerization, thereby reducing mtDNA leakage and AIM2 inflammasome activation, suppressing neuronal pyroptosis and protecting against cerebral ischemic injury. ABSTRACT Ischemic stroke is one of the

Microenvironment‐Responsive Biomimetic Hydrogels Delivering Cistanche Deserticola‐Derived Nanovesicles for Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
An injectable, microenvironment‐responsive hydrogel (HAPOCS@CDNVs) is developed for sustained delivery of Cistanche deserticola‐derived nanovesicles (CDNVs). By scavenging ROS, restoring mitochondrial function, and attenuating SASP, this platform effectively suppresses nucleus pulposus cell senescence and facilitates extracellular matrix reconstruction,

SynAtlas: A Safe and Versatile Platform for Rapid Organ‐Scale Tissue Clearing and 3D Atlas Mapping

open access: yesAdvanced Science, EarlyView.
An orthogonal synergy design principle integrates lipid solubilization, protein hydration modulation, and refractive‐index matching within a unified aqueous clearing system. This modular strategy enables rapid, low‐hazard, and broadly compatible tissue clearing while preserving molecular signals, supporting multiscale three‐dimensional imaging across ...

Cell Segmentation Beyond 2D—A Review of the State‐of‐the‐Art

open access: yesAdvanced Intelligent Discovery, EarlyView.
Cell segmentation underpins many biological image analysis tasks, yet most deep learning methods remain limited to 2D despite the inherently 3D nature of cellular processes. This review surveys segmentation approaches beyond 2D, comparing 2.5D and fully 3D methods, analyzing 31 models and 32 volumetric datasets, and introducing a unified reference ...

Ultrastructure of the Developing Sunflower Microscope

open access: yes, 1977
An investigation of the ultrastructure revealed that most of the mitochondria of the microspore and mononuclear pollen grain of the sunflower are situated on the surface of the outer membrane of the nuclear envelope, frequently in direct contact with ...
